Re: [Gumstix-users] Howto use wifistix ?

[mike h. <mr...@gm...>]

Samuel,

Try setting the options with one call to iwconfig and connecting with a
second call to iwconfig.
Something like this:

   iwconfig mwlan0 rate 54M txpower 100mW
   iwconfig mwlan0 essid any

for example.  I found that it won't work to set options or keys in the same
invocation as the connect with essid.
Not sure if this is the problem you are having, but it caused me trouble
until I figured it out.
